What Does X Equal To In This Problem

Answers

Answer 1

Using the triangle, we can find the angle lengths and using those and trig ratios, find the side lengths. Lets say the top side length is "y".

Using the Law of triangles, we can find the missing angle from 180-90-70=20 deg.

Then we can use the Law of sines,

sin(70)/13=sin(20)/y

y=sin(20)*13/sin(70)

y=15.34

Finally, we use the Pythagorean Theorem, (13)^2+(15.34)^2=x^2

x = 20.1

David and his dad are building a room in the basement. They want the
room to have an area of 150 ft?. If one wall is 11.25 ft. long, how long must the other
wall be? Show your work.

Since you’re trying to find the area the equation would be 150=11.25x and you divide by 11.25 to get x alone and you would get 13.33333 so about 13 1/3

A tennis court for singles play is 78 feet long and 27 feet wide. Part 1 out of 3 The court for doubles play is 9 feet wider than the court for singles play. How much more area is covered by the tennis court used for doubles play? The tennis court used for doubles play covers square feet more area than the court used for singles play.

Answers

Answer:

702 ft^2

Step-by-step explanation:

Steps to answering this question

1. determine the area of the singles court

area of a rectangle = length x width

27 x 78 = 2106 ft^2

2. Determine the width of the doubles court

27 + 9 = 36FT

3. Calculate the area of the doubles court

area of a rectangle = length x width

78 x 36 = 2808 ft^2

Find the difference in areas

2808 - 2106 = 702 ft^2

Ruth develops a blueprint with the help of a triangle. The longest side of the instrument measures 14 inches and one of the sides measures 12 inches.

Answers

Answer:

The other side is sqrt(52) units or 7.21110255 units

Step-by-step explanation:

I'm assuming you want the other side of the triangle, which you would use the Pythagorean theorem for.

a^2 + b^2 = c^2

12^2 + b^2 = 14^2

144 + b^2 = 196

b^2 = 52

b = sqrt(52) or 7.21110255
